UNITED STATES THEODORE CARL MASTERS, OF NEW YORK, N. Y.

BATTERY TERMINAL.

Application filed January 12, 1922. Serial No. 528,784.

To all whom it may concern:

Be it known that I, THEODORE C. MASTERS, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Battery Terminal, of which the following is a full, clear, and exact description.

. This invention relates to a battery terminal, and has for an object the provision of means whereby the terminal may be very quickly and easily applied to a battery post.

Another object resides in the provision of means which not only is easily applied but results in a very firm and secure contact between the terminal and the post.

A further object resides in the particular construction and arrangement of parts which are hereinafter described and claimed and shown in the accompanying drawings.

The invention is illustrated in the drawings, of which- Figure 1 is a plan view of a battery post with the terminal applied showing the cooperating parts in one position before the terminal has been secured or clamped to the post.

Fig. 2 is a section taken on the line 2-2 of Fig. 1.

Fig. 3 is a plan view showing the various parts in a second position, in which the parts have been tightly clamped on to the post.

Fig. 4 is a plan View of the terminal sleeve. i

Fig. 5 is a section taken through the collar 8.

The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and in the character of the materials used may be adopted without departing .from the spirit of the invention.

The invention in general comprises a terminal the end of which is in the form of a split sleeve which can be readily placed over a battery post. Over this sleeve is placed a collar, and by turning the collar the sleeve is clamped firmly on to the post. This clamping action is effected by reason of the fact that, preferably, the outer walls of the sleeve and the inner walls of the col-.\

lar which engage each other are provided with cam surfaces which coact and result in the clamping action. The collar may be turned by hand or by any suitable tool, as desired.

To this end, the invention comprises a terminal plate 1 provided at one end with a socket 2, or other tubular portion, to receive a wire 3. This plate is provided with an upstanding, post-engaging sleeve 4, preferably split. The walls of this sleeve are provided on their outer faces with cam surfaces such as 5 and 6. The plate 1, however, extends, as represented at 7, beyond the edges of the surfaces 5 and 6 to rec'eiveand support a collar 8. This collar 8 is provided with projections or teeth, such as 9, with which a tool, such as a wrench 10, may engage to turn the collar. lar are provided with a plurality of cam surfaces such as 11 and 12 which, as shown in Fig. 3, are preferably knurled to provide a good grip ing action. These surfaces 11 and 12,-as s own in Fig. 1, lie adjacent the surfaces 5 and 6 on the sleeve 4. When the sleeve is placed over a battery terminal, which is represented by the numeral 13, and the collar is placed thereo-ver, the relative positions are represented by the parts as shown in Fig. 1. When the wrench, however, or other tool, turns the collar to the position shown in Fig. 3 then the cam surfaces have coacted to force the sleeve 4 tightly around the post 13, as shown in Fig. 3. The fact that the inner edges of the collar .are knurled will enable this clamping grip to be maintained better.

In operating the device, therefore, it is The inner faces of the colmerely necessary to place the sleeve over the post, then place the collar over the sleeve and give it a turn or part of a turn in a predetermined direction. To release the terminal, it is merely necessary to reverse the action by turning the collar in the opposite direction.

. It is also to be noted that the ends ofthe I walls of the sleeve, as designated by the numerals 14-and 15, are wider than theyare at the points designated by the numerals 16 acts to assist in releasing-the sleeve from the post when moved in the opposite direction.

What I claim is:

1. A battery terminal which comprises a split sleeve to be placed over a battery post, cam-shaped outer walls on said sleeve, a collar, and cam-shaped inner walls on the collar to engage with the walls of the sleeve when the collar is placed thereon to clamp the sleeve on the post when the collar is moved on the sleeve in a given direction.

2. A battery terminal which comprises a terminal plate, a split sleex e thereon having cam surfaces on its outer face, a collar to be placed over the sleeve and having cam surfaces on its inner face to engage with the cam surfaces on the sleeve, the collar when moved in one direction effecting the clamping of the sleeve on the post or other support, and shoulders on the collar and sleeve engaging when the collar is moved to release the sleeve from the post whereby the releasing of the sleeve from the post is assiisted by the direct engagement of the shoulers.

3. A battery terminal which comprises a terminal plate, a split sleeve thereon, a collar tobe placed over the sleeve, means on the sleeve and collar engaging when the collar is moved in one direction to clamp the sleeve on the post, and means on the collar and sleeve engaging when the collar'is moved in the opposite direction to release the sleeve
